HI, 
Sorry Carl, I received your message in my spam folder. Sarah proposed me a good example of code.
Thank you

Please read the posting guide and provide a (small) reproducible example 
of your data. 

The statement "...output does not seem good."  is not very useful. 
Please explain what you would like the polygon area to look like, and 
why you don't like the way it came out.  Links to posted images of the
chart would help too.

Hi everybody, 
I have a matrix with 3 columns (Date, MeanArea and SdArea). I want to 
draw a figure showing the variable MeanArea in terms of the Date. But 
instead to use the variable SdArea as bar error, I want to use “polygon 
error”. I use this code but the output does not seem good. 
Poly<read.table("C:\\Users\\Momadou\\Documents\\AreaMonthly.csv",sep=";",dec=",",header=TRUE) 
Poly 

y <-MeanArea 
x <-SdArea 
z <-Date 

matplot(x,cbind(y,z),type="n") 
polygon(c(x,rev(x)),c(y,rev(z)),col="grey50") 
Thank you in advance
